Detailed Documentation

STL-style Sequence Iterator inherited from the CvSeqReader structure

Construction

SeqIterator()

the default constructor

SeqIterator(
    const Seq<_Tp>& seq,
    bool seekEnd = false
    )

the constructor setting the iterator to the beginning or to the end of the sequence

Methods

_Tp&
operator*()

returns reference to the current sequence element

const _Tp&
operator*() const

returns read-only reference to the current sequence element

SeqIterator&
operator++()

moves iterator to the next sequence element

SeqIterator
operator++(int) const

moves iterator to the next sequence element

SeqIterator&
operator+=(int delta)

moves iterator forward by the specified offset (possibly negative)

SeqIterator&
operator--()

moves iterator to the previous sequence element

SeqIterator
operator--(int) const

moves iterator to the previous sequence element

SeqIterator&
operator-=(int delta)

moves iterator backward by the specified offset (possibly negative)

void
seek(size_t pos)

positions the iterator within the sequence

size_t
tell() const

reports the current iterator position
